UFC Vegas 124, The Morning After: Reborn Walker Finds Heavyweight Home

At UFC Fight Night (UFC Vegas 124) held at the UFC APEX in Las Vegas on November 7, 2026, Johnny Walker of Brazil knocked out Waldo Cortes-Acosta of the Dominican Republic in a heavyweight bout. Walker, who originally made his name at light heavyweight with a series of spectacular first-round finishes beginning in 2018, has now found success after moving up to the heavyweight division. The victory marked a notable comeback for Walker, whose early UFC career stalled after a promising start.
